Abstract: PURPOSE:To allow a main-body side CPU to access the entire space of, for example, a CPU-card side memory by selecting mapping registers and allowing the main-body side CPU to access the entire space of the memory of another CPU. CONSTITUTION:The memory 4 on a CPU card which has a CPU 3 of architecture different from the main-body side CPU 1 (or CPU operating an OS) is divided into banks B-0 to B-4 in constant units.

Title: Electrophotographic sensitive body
Inventor: YOSHIHARA YOSHIYUKI
IPC: G03G5/04
Filed: 1989-06-08
Abstract: PURPOSE:To attain the higher sensitivity by expressing the characteristic matching of a charge generating material and a charge transfer material by the difference in the work functions thereof with respect to the dependency on electric field intensity. CONSTITUTION:The film thickness of the charge transfer layer of the electrophotographic sensitive body laminated with the charge transfer layer on a charge generating layer is increased, by which the capacity of the photosensitive layer is decreased and the required surface potential is obtd. with the smaller charge quantity. If, however, the efficiency of the generation and implantation of photocarriers depends largely on the electric field intensity, this charge transfer layer has the tendency that the sensitivity is lowered by increasing the film thickness of the charge transfer layer. The work function WFCG of the charge generating material and the work function WFCT of the charge transfer material are set at the relation of inequality I in order to sufficiently lessening the dependency on the electric field intensity in the generation and implantation of the photocarriers by decreasing the film thickness of the charge transfer layer to <=25mum. The higher sensitivity is easily attained in this way.

Title: Semiconductor memory
Inventor: KOMORI KAZUHIRO
IPC: G11C16/06
Filed: 1983-08-12
Abstract: PURPOSE:To improve the writing efficiency and to ensure the satisfactory reading, etc. in an easy-to-form constitution, by forming the pull-up resistance of a writing circuit with a prescribed MISFET and connecting the pull-up resistance in series to a breaking MISFET of a read mode. CONSTITUTION:The pull-up resistance of a writing circuit 2 is formed with a polycrystalline silicon FET obtained by doping impurities into a channel area. The resistance value of the pull-up resistance can be easily selected with easy formation, and the writing efficiency is improved by the conversion into the optimum low resistance. An MISFET8 which is cut off in a read mode is connected in series to the pull-up resistance. Thus the pull-up resistance is substantially set at a high level in the read mode. This ensures the satisfactory reading with small power consumption. In addition, an MISFET is formed on an insulated film owing to the constitution of polycrystalline silicon MISFET of the pull-up resistance. This prevents a latch-up phenomenon.

Abstract: PURPOSE: To make one pressure disk diverge from the other in the direction of rotation of a bead core and also to make them converge mutually in the direction of the axis of rotation of the bead core so that joining can be ensured, during the time when the disks are in an idle state and set free from a driving means and a filler is applied. CONSTITUTION: After a bead core 5 engages with a centering disk 2a and a fastening flange 2b between them, a friction wheel 7 is made to exert a force of thrust on the outer peripheral end edge of the flange by a fluid cylinder 11 and sets a degree of pulling of the bead core 5. At the same time, an elastic filler 34 is inserted between pressure disks 17 and 18 and the bead core 5. In a state of being separated by a prescribed distance from each other through the intermediary of a regulating means 23, at this time, the pressure disks 17 and 18 are brought into contact with the lateral parts of the filler 34 by cylinders 22 and the bottom part of the filler 34 is pressed against the outer circumference of the bead core 5.  The pressure disks 17 and 18 are directed so that a direction between outer peripheral projections 17a and 18a may increase gradually toward the direction of rotation of the bead core 5 in the area of contact thereof with the filler 34. According to this constitution, it is made possible to apply the filler effectively on the bead core without causing any dimensional change in the filler itself.

Filed: 1987-06-12
Abstract: PURPOSE:To preclude the contrast decrease of a spectral reflection factor by measuring reflected light nearly parallel to the optical axis of a light measurement system in reflected light from a projection and recess part. CONSTITUTION:Luminous flux from a light source 1 illuminates a body 7 to be measured through a condenser lens 2, a 1st half-mirror 4, and an objective 5. Then its reflected light is transmitted through the lens 5 and mirror 4, reflected by a 2nd half-mirror 8, and then guided to a spectroscope 10. Here, the effect of interference between reflected light beams from the top surface and bottom surface of a trench is utilized to detect the period of the peak of the spectral reflection factor, thereby calculating the depth of the trench. For the purpose, the diameter of a pinhole 9 and the focal length of the lens 5 are set properly to measure only the reflected light nearly parallel to the optical axis S of the light measurement system, and then the eclipse of luminous flux at the upper part and on the side face of the trench is reduced to prevent the contrast of the spectral reflection factor from decreasing, thereby measuring the depth of the trench with high accuracy.

Title: Heat exchanger
Inventor: SAEKI TAKAO
IPC: F28D15/02
Filed: 1986-06-23
Abstract: PURPOSE:To prevent the temperature of oil from pulsating by introducing oil under a high-temperature condition into an oil reservoir part at the longitudinal central part of a heat absorbing section of a heat pipe to guide the same to the heat absorbing section of the heat pipe, and leading out oil which is in a low-temperature condition from both sides of said heat absorbing section into an oil tank. CONSTITUTION:Oil 1 which is in a high temperature condition is introduced into an oil reservoir 16a disposed at the central part of guide means 16 disposed within an oil tank 2 via an inlet pipe 17. The oil 1 under a high-temperature condition is horizontally guided to the heat absorbing section 13a of a heat pipe 13 and circulates on both longitudinal sides. By the repetition of vaporization and liquefaction of a working loquid within the heat pipe 13, the heat of the high-temperature oil 1 passing the heat absorbing section 13a is transported to a heat radiating port 13b. Accordingly, the high-temperature oil 1 which has flowed into the oil reservoir 16a is converted into a low-temperature oil 18 in the heat absorbing section 13a and is led out into an oil tank 2 from both longitudinal sides. Thus, the oil of a high temperature condition is naturally controlled by a temperature difference between the heat absorbing section side and the heat radiating section side and stable oil free from pulsation is obtained.
